It tells the history of first the Precision Endo Syringe, then of the Multi-Mode Precision Endo Syringe and now (April of 2002) the newest iteration of the Precision Endo Syringe is the Multi-Mode Cartridge Endo Syringe.

The article continues:

Yes, it's true.

After almost 20 years

the Precision Endo Syringe
is now obsolete.

Oh, it's as good as it always was it's just that there is a better one on the market now.

It's called the

Precision Endo Multi Mode Syringe.

A lot of things have changed since Special Products, Inc. began selling the Precision Endo Syringe in January of 1978.

It was acceptable in 1978 to load a syringe with cement and change needles between patients.

Now the syringe must be emptied between each patient, sterilized and reloaded.

In a busy practice this ofter necessitates multiple syringes.

So we now supply multiple cement barrels with each syringe.

Over the years we have learned the fine points of flow control.

One of the main factors is the amount of air incorporated into a barrel full of cement.

If the quantity is smaller, the cement flows better and can be controlled better.

So we made the barrels smaller.

Once the apex is sealed we needed a way to back-fill faster, so now you can switch the barrel off the Precision Syringe and attach it to the driver of the PDL intraligamentary syringe.

This speeds up back filling.

With many dentists using a combination of cement and gutta percha filling it is now possible to load a spare barrel with gp, attach a needle, heat it and when it comes time to back fill, put the barrel on and back fill with gp, condensing it as you go.

Today almost everyone uses gloves.

This eliminated the need to have knurling on the knobs of the syringe.

All that knurling does is get dirty.

So we made the knobs smooth.

It is desirable to have the plunger fit as closely as possible to the inside of the barrel and have a hollow ground plunger which fits the ball valve precisely.

When the plunger rod is threaded the rod has to be smaller.

So we made a separate threaded driver and plunger rod. This means less wear and tear on the threads and a tighter fit.

Ergo, better control.

The syringe is still made entirely of stainless steel for durability and long life.

We are currently working on two attachments for the syringe.

The first will be a very small barrel that will give it about 100 times the control and thus make it possible to pressure fill canals by calculating the volume of the canal in advance and then delivering exactly the right amount of cement.

We call this the Volume Control Method.

The second is a barrel that can be used with the currently available composite nozzles.
